With just 124 days to go until Americans choose a new president, Democrat Barack Obama has no public events on his schedule Thursday, after spending a day campaigning in Colorado Springs. Meanwhile, Republican John McCain continues what he insists is a non-campaign trip south of the border.

He plans some sightseeing in Mexico City Thursday morning before talks with Mexico's President Felipe Calderon and has an informal news conference.

McCain's Latin America trip this week has centered on the subject of free trade, which he supports.

Wednesday McCain was in Colombia, where the government is getting enormous praise for its dramatic rescue of more than a dozen hostages, including three Americans. McCain says he was briefed on the rescue plan in advance. He and Obama are both congratulating Colombia and its president over the successful outcome.
